Is there any rime or reason to the cities that Google chooses to put fiber into? Is it a matter of more friendly local government, less resistant local teleco's, a combination thereof or some other factors? Just seems the locations aren't exactly tech hubs so I'm trying to get a better idea of how the expansion works.
Friendly local government is a big factor. For example: Google looked at Seattle's NIMBY laws regarding utility boxes on sidewalks (each requiring a lengthy community approval process) and said, "Nope!" Seattle's new mayor is now looking how to streamline the process to make the city more Google friendly, should the opportunity arise again.
Which is good, as sidewalks are for walking, not utility installation pads.
In much of the UK outside conservation areas BT has powers to install cabinets as it sees fit. Combined with utility poles there are now some pavements on my town impassable to prams.
